摘要

Abstract

This work aims to solve the problems of low reaction activity of Cu-based catalysts and agglomeration of active centers in acetylene hydrochlorination. Cu-based catalysts supported by NP co-doped activated carbon (AC) with different content (

Cu-

NP/AC) were manufactured and applied in the acetylene hydrochlorination reaction. It was found that the doping of carriers N and P induced the transformation of Cu

to Cu

and the catalytic activity was markedly improved. Under the optimal reaction temperature of 220 ℃

the gas hourly space velocity (GHSV) of C

was 90 h

-1

and

HCL

was 1.15. The initial activity of the 5%Cu-30NP/AC catalyst reached 95.59%. Through some characterization methods showed the addition of N and P improved the dispersion of Cu in carbon

which increased the ratio of Cu

/Cu

. The measurement results confirmed that the chemisorption capacity of

Cu-

NP/AC for C

decreased slightly

and the chemisorption capacity for HCl increased significantly

which was the reason for the i

ncreased activity of the catalyst. The conclusion provides a reference for the development of acetylene hydrochlorination Cu catalyst.
